Description

Recumbent bike steering apparatus

The present invention relates to a steering apparatus of a recumbent bicycle, and more particularly, to a steering apparatus of a recumbent bicycle whose structure is improved to enable steering control reflecting the weight shift of the occupant.

Recumbent bikes are designed for riding with your back. In recent years, attention has been focused on recumbent bicycles for ergonomic reasons. That is, in the case of the recumbent bicycle, the weight of the occupant is comfortably distributed over a large area supported by the back and the hip. In a traditional erect bike, the entire weight is concentrated on a part of the sciatic, the feet, and the hands.

Recumbent bikes also have an aerodynamic advantage due to their small frontal area due to their forward and backward positions.

As a kind of recumbent bicycle, a two-wheeled three-wheeled bicycle has a structure in which a pair of front wheels are connected by one link so that the front body cannot reflect the weight shift of the human body when turning. It has been acting as a factor that hinders the safety of the occupants.

Recumbent bicycles are expensive and are stored indoors after use rather than outdoors. However, the recumbent bicycle has a disadvantage that it is not easy to store the room because the size of the large bike is not easy to store in the trunk of the vehicle.

The present invention has been made to solve the above problems, an object of the present invention is to provide a steering apparatus of a recumbent bicycle capable of steering control reflecting the weight shift of the occupant.

Another object of the present invention is to provide a steering device of a recumbent bicycle that can be folded so that its volume can be reduced.

Steering device of the recumbent bicycle according to the present invention for achieving the above object, the steering wheel supports a pair of wheels arranged in a symmetrical position with respect to the center bar of the chassis, the width between the pair of wheels A bracket unit arranged to extend along the direction; And a link unit that is dynamically connected to the handle and the wheel so that the pair of wheels can be steered according to the operation of the handle, and is installed to be relatively rotatable with the center rod together with the center rod. The link unit is operated by a steering wheel operation to enable steering of the pair of wheels, as well as to configure the link unit to steer the pair of wheels when the center rod is tilted by the weight movement of a passenger. It is done.

The center rod is preferably provided with a rotation rod rotatably installed on the bracket unit so that the center rod can be tilted with the center rod when the weight of the occupant moves.

The bracket unit may include a pair of support brackets for steering the wheels; A binding bar that couples the pair of support brackets to be folded and unfoldable and is coupled to the rotation rod so as to be relatively rotatable; And bracket-side fastening means for selectively enabling folding and unfolding of the pair of support brackets to the center bar.

The link unit may include: a first link having one end connected to any one of the pair of wheels and the other end foldable and unfoldable to the center rod; A second link, one end of which is connected to the other of the pair of wheels and the other end of which is foldable and unfoldable to the center rod; And link-side binding means for selectively enabling folding and unfolding of the first link and the second link with respect to the center rod.

In the steering device of the recumbent bicycle according to the present invention having the configuration as described above, as the weight shift of the occupant is performed by the steering angle of the pair of wheels, the so-called 'cornering' is smoothly performed, The advantage that the overturning phenomenon of the bicycle due to the inconsistency of the cornering can be remarkably eliminated, and the steering control of a pair of wheels is possible only by moving the weight of the occupant, thereby enabling active cornering rather than steering wheel. The curve has the advantage of further improving the stability and running performance during driving.

In addition, the present invention, by operating the binding lever to fold the pair of wheels with the support brackets and the first link and the second link to the center rod side, so that the user can easily store the product in the vehicle or indoors Has an advantage.

As shown in these figures, the steering apparatus of the recumbent bicycle according to the present invention comprises a bracket unit 20 and a link unit 30.

The bracket unit 20 supports a pair of wheels F, which are disposed at symmetrical positions with respect to the center bar 10 of the chassis, to be steerable, and has a width between the pair of wheels F. It is arranged long along the direction.

The bracket unit 20 supports the pair of wheels F in a steerable manner through a pair of connecting brackets 40. Here, steering means a state in which the pair of wheels F can be rotated along an axis in the vertical direction. The wheels F are rotatably supported by the connection brackets 40, and the handles H are connected to enable steering control of the pair of wheels F.

The bracket unit 20 may be integrally formed with one component to support the pair of wheels F, but in the present embodiment, a pair of brackets may be used to enable a folding operation for volume reduction. Support brackets (21) and (22), the binding bar 23 and the bracket-side binding means 24 is provided.

Any one of the pair of support brackets 21 and 22 has one end connected to any one of the pair of connection brackets 40 and the other end is bound to the binding bar 23. do. The other one of the pair of support brackets 21 and 22 has one end connected to the other one of the pair of connection brackets 40, and the other end of the pair of support brackets 21 and 22. Bound to.

The bracket-side binding means 24 serves to selectively bind and release the other end of the pair of support brackets 21 and 22 that are bound to the binding bar 23. As the bracket-side fastening means 24 in this embodiment, a fastening lever which is a clamping member well known to those skilled in the art is employed.

The link unit 30 is operatively connected to the handle H and the wheels F, thereby enabling steering control of the pair of wheels F in accordance with the operation of the handle H. . The link unit 30 is rotated with respect to the bracket unit 20 together with the center rod 10 so that the inclination of the vehicle body due to weight movement of the occupant can be actively applied to the pair of wheels F. FIG. do.

That is, the present invention not only enables general steering control, but also derives the advantage of enabling steering control reflecting the weight movement when the weight of the occupant is moved. Specific means for deriving such advantages will be described below with reference to FIGS. 5 to 9.

The center rod 10 has a rotation rod 11 rotatably installed on the bracket unit 20. The rotating rod 11 is inclined together with the central rod 10 when the weight of the occupant moves.

First, a description will be given of the principle that the inclination of the pair of wheels F and the weight shift of the occupant occur together with the manipulation of the handle H. That is, as shown in Figures 5 and 9, the occupant manipulates the handle (H) so that the rotating rod 11 together with the central rod 10, inclined at an angle as shown by the dotted line of Figure 5 When the handle (H), the link unit 30 and the pair of wheels (F) are connected to each other, as shown in FIGS. 7 and 8, the pair of wheels (F) are at an angle. It will tilt. As the angle of inclination of the pair of wheels F, the rotation rod 11 is inclined with respect to the axis of the up and down direction, the weight movement of the occupant is made.

In this case, as the weight shift of the occupant is made as much as the steering angle of the pair of wheels F, the so-called 'cornering' is performed smoothly, so that the cornering is not smoothly overturned by the bicycle. The phenomenon can be remarkably eliminated.

Next, the principle of enabling steering control of the pair of wheels F by the weight movement operation of the occupant, not the manipulation of the handle H, will be described. That is, as shown in FIG. 6, when the occupant moves the weight so that the rotation rod 11 is inclined at an angle with the center rod 10, the link unit 30 is the pair of wheels F. FIG. Since the pair of wheels (F) is inclined by a predetermined angle.

In this case, steering control of the pair of wheels F is possible only by moving the weight of the occupant, thereby enabling active cornering instead of steering wheel H, thereby ensuring stability and driving performance when driving a curved section of the bicycle. Can be further improved.

Meanwhile, in the present embodiment, as illustrated in FIGS. 10 to 12, the collapsible structure of the pair of wheels F, which occupies a large volume of the bicycle, is adopted.

That is, the link unit 30 includes a first link 31, a second link 32, and a link side binding means 33. One end of the first link 31 is connected to any one of the pair of wheels F, and the other end of the first link 31 is connected to the central rod 10 so as to be folded and unfoldable. One end of the second link 32 is connected to the other of the pair of wheels F, and the other end of the second link 32 is connected to the central rod 10 so as to be folded and unfoldable. As for the link-side fastening means 33, like the bracket-side fastening means 24 described above, a fastening lever which is a clamping member well known to those skilled in the art is employed.

In this embodiment having such a configuration, when the normal driving is made in the state as shown in FIG. 10, and storage is required, as shown in FIG. 11, a pair of support brackets 21 ( After the state of engagement between 22 and the engagement bar 23 is released and the state of engagement of the center rod 10 of the first link 31 and the second link 32 is released, as shown in FIG. As described above, the pair of wheels F are folded together with the support brackets 21 and 22 and the first link 31 and the second link 32 toward the center rod 10 side, thereby allowing the vehicle of the recumbent bicycle to be folded. Or to facilitate indoor storage.
